Checkout for Concurrent update UDP

[Jarus Bosman]

Good day,

This is going to sound counter-intuitive, but I have my reasons.

I need a UDP that will check if an item is currently checked out, or if a branch version exists in any state of a project. It would be helpful if it can also provide the user to whom the item is checked out. In certain circumstances I want to prevent concurrent check-outs. However, I don't want to remove concurrent checkouts altogether for that project.

Kind regards,

Jarus

Hello Jarus,

You should check out the "hsv" command.  It's similar to the "find versions" tool in Workbench.  I think you have to give it a specific state name in your search, but if all new versions originate from the same state, you can search that state and find it no matter where the package is in the lifecycle.  Here's where you can read more: hsv Command-Select Version

Let me know if this helps.

Thanks :)

Hi Melinda,

This solution would work if I was able to send the item name and extension to my UDP. However, I only have the ["version"] system variable available, which includes the full path and version number, separated by a semicolon. I find it redundant to have to strip out the item name and extension, this should be provided by Harvest when invoking UDP's. Or am I missing something?

Regards,

Jarus

Which operating system is your UDP running in?  I have an idea of maybe running HSV at a broader level - like getting all the files in the state and then "grepping" the result for the file you want.  I will do some testing to see if this might work for what you want to do.

Thanks :)

Hi Melinda,

We're running on Linux, so my UDP runs a bash script. Your solution above doesn't help, as I still don't have the filename and extension. I've managed to parse it like this:

#!/bin/bash

# Input string without drive letter (e.g., "\path\to\file.txt;1.23")
input_string="\path\to\file.txt;1.23"

# Replace backslashes with forward slashes
normalized_path=$(echo "$input_string" | sed 's/\\/\//g')

# Extract file name and version number
file_name_with_extension=$(basename "$normalized_path" | cut -d ';' -f 1)
version_number=$(basename "$normalized_path" | cut -d ';' -f 2)

# Extract file name without extension
file_name_without_extension=$(echo "$file_name_with_extension" | cut -d '.' -f 1)

# Display results
echo "File Name with Extension: $file_name_with_extension"
echo "File Name without Extension: $file_name_without_extension"
echo "Version Number: $version_number"

I still believe there should be a system variable that returns just the item's filename and extension, without the path and version. I need this in almost all of my UDP's.

Kind regards,

Jarus

Do you know the name of the file you're looking for?

No, because it's a UDP that can be run on any item. That's why I need a System Variable that returns the item's filename and extension.

You're right.  Harvest does not offer a system variable that can return only the file name without path or version.  That would have to be an enhancement request.

For now, all I can offer is an easier way to parse the results you get back from the [version] variable so that you get the parts of the result you need.  You and I are thinking along similar lines.  Here's what I came up with:

$ cat test.sh
foo=$1
wholename=$(echo ${foo##*\\} | cut -d';' -f1) ; echo This should remove path and version: $wholename
filename=${wholename%.*} ; echo This should be the filename only: $filename
extension=${wholename##*.} ; echo This should be the file extension: $extension
$

And it produces this result:

$ ./test.sh "\SampleRepository\DOCS\README.1.2.3.TXT;1"
This should remove path and version: README.1.2.3.TXT
This should be the filename only: README.1.2.3
This should be the file extension: TXT
$

It works with traditional filenames as well:

$ ./test.sh "\SampleRepository\DOCS\README.TXT;1"
This should remove path and version: README.TXT
This should be the filename only: README
This should be the file extension: TXT
$

Let me know if this helps.

Hi Melinda,

I finally had some more time to work on this, and I've now made it work using your hsv suggestion. I simply get the latest in branch and latest in trunk for the Development view using hsv. If the latest branch version < latest trunk version, it means that all changes have been promoted to Production and I exit 0 my script. If latest branch version > trunk version, there are still some changes not in production, so I then check if the current user attempting the checkout is the same as the user that made the branch change (info retrieved from hsv). If the user is the same, exit 0, else exit 1. Since this is pre-link for checkout, checkout will fail if another user made changes. This prevents concurrent update.

I've used awk successfully in parsing the hsv results to retrieve all the fields I need (modify user, package name, version, modified date).

Thank you very much for your help!

Regards,

Jarus
